Abstract: A microgeometric electric field machine includes arrays of conductors formed on or carried by a plurality of substrates. The conductors on a first group of substrates carry electrical charges, with alternate conductors being charged positively and the other conductors being charged negatively. A second group of substrates are interleaved with the first group in close proximity therewith. Also included is a voltage source for successively supplying alternate positive and negative electrical charges to the conductors of the second group of substrates. Effectively a pattern of alternate positively and negatively charged conductors is established for the second group of substrates and these patterns are caused to move, relative to the substrates, along the arrays of conductors to produce "moving" electric force fields which cause one group of substrates to move with respect to the other group. The substrates may be in the form of stacked discs with the conductors being radially positioned thereon, where one group of discs is caused to rotate with respect to another group. Alternatively, the substrates may be in the form of stacked planes with the conductors positioned in parallel thereon, where one group of planes is caused to move linearly with respect to the other group, and in a direction perpendicular to the conductors. The configuration of the substrates, positioning of the conductors, and inter­leaving of the substrates and conductors could take a variety of forms.

Abstract: A display processor in a raster graphics display system includes a transformation, clipping and mapping feature which controls the transformation, clipping and mapping of graphics data. A control byte contains 5 bits identified as: M- Window to viewport mapping; P-perspective projection; D-2D/3D mode; T-transformation; and C-clipping. Each bit in the control byte is tested to determine what operations are to be performed on the figure to be drawn. For example, if the D bit is one, indicating a three dimensional figure and the T bit is one, indicating transformation, and the C bit is one, indicating clipping, the P bit determines whether the clipping will be perspective or non-perspective clipping and the M bit determines whether the figure to be drawn is to be mapped to the view port.

Abstract: A self-cleaning canister type filter (1) comprises a cylindrical canister enclosure (3) which has, at one end, end plate (2) with fluid inlets (4) and outlet (6) therein. A spring-loaded hollow annular piston (30) is slideably mounted on the exterior of a central tubular cylinder (10) and within an upper cylinder (28) for a downward movement against a compression spring (32) to initially force a back-flow of filtered fluid through a filter element (14), lifting contaminant particulate solids from its filtering surface (15). An inlet valve opening (64) is opened to fluid flow when piston (30) attains a compressed position. Filter element (14) is closely spaced to the canister enclosure inner wall surface (9) for rapid flow of fluid over the inlet surface (15) of the filter element (14) to scour solids to a sump (5) in the lower portion of the canister enclosure (3). A lower spring-loaded piston (18) communicates with sump (5) and is forced upward by entering contaminated fluid until an attached sleeve valve piston (23) slideably mounted in tubular cylinder (10) opens to permit filtered fluid to exit the filter (1), resulting in normal filtration flow of fluid through filter element (14).

Abstract: A plurality of transducers (40) are carried by a logging sonde (10) for transmitting and receiving acoustic pulse signals. The transducers are operated as a plurality of arrays, each array including four trans­ducers disposed along an arc extending circumferentially of the sonde, two transducers being operated as transmit­ters (T) and two as receivers (R). The transducers are arranged, for example in helices, so that the arcs com­plete a circumference about the sonde. The amplitudes of the received acoustic pulse signals are measured, the travel time of an acoustic pulse signal travelling bet­ween the two receiving transducers is determined, and the attenuation of the acoustic pulse signal travelling between the two receiving transducers is thereby deter­mined. When the sonde is logging a cased borehole, the attenuation signal for each sector is representative of the quality of the cement bond between the casing and the borehole in that respective sector. This permits the azimuthal location of channels or fissures between the casing and the cement.

Abstract: In a distributed environment several data pro­cessing systems are interconnected across a network system (3). A distributed services program installed on the systems in the network allows the processors to access data files (5) distributed across the various nodes (A,B) of the network without regard to the location of the data file in the network. 
     The processing system accessing the file, re­ferred to as the client processing system, utilizes a client cache (12B) within its operating system (11B) to store the data file. Utilizing the client cache minimizes the number of reads and writes that must go over the network (3) to the server processing system where the file physically resides. 
     The system and method of this invention prevents a process in the client processing system from access­ing data in the client cache that has been modified at another node (A) in the network. The blocks of data in the client cache (12B) are tested for validity in the client processing system by using modification times as measured by the server processing system. If the cache data blocks are determined to be valid, the data is accessed from the client cache. If the cache data blocks are determined to be invalid, the data blocks are discarded, and the file is accessed from the server processing system.

Abstract: A method for regulating access by concurrent transactions to hierarchically-related resources distributed about a loosely-coupled multiprocessor system is disclosed. Lock requests are first decided by a local lock manager (2a...2n) and then by a central lock manager (1). When a single local lock manager (2a...2n) holds locks on a resource, that local lock manager has sole interest in the resource. While a lock manager has sole interest in a resource, it can acquire locks subsidiary to the resource without consulting with the central lock manager (1). Sole interests of objects are shifted dynamically for optimising local control of objects, thereby minimising communication and transaction wait time.

An image processing circuit replaces each image pixel vlaue [P(i,j)] from an image reconstruction means (32) with an improved pixel value p*(i,j) defined as follows:     where G(i,j) is a weighting function uniquely defined for each pixel (i,j), 7 is the mean of pixel values of neighboring pixels and  n  is the mean image noise. The weighting function is based on an image data noise variance and a pixel value variance V(i,j) corresponding to the same pixel. The data noise variance is derived by comparing a data value difference between each data value d(x,y) and its neighboring data values in a data memory (30). The smallest data value difference is indicative of the image noise variance. Each pixel variance is indicative of the difference between a corresponding pixel value and the neighboring pixel values.
